1.The methods that a community devises to perpetuate itself comeinto being to preserve aspects of the cultural legacy that thatcommunity perceives as essential. 一个社会所创造出来藉以使其自身生生不息、恒久不衰的方法得以形成产生，以保存在这个社会看来具有本质意义的文化遗产的各个方面。 2.Because the potential hazards pollen grains are subject to asthey are transported over long distances are enormous，wind pollinated plants have，in the view above，compensated for the ensuing loss ofpollen through happen stance by virtue of producing an amount of pollenthat is one to three orders of magnitude greater than the amount produced by species pollinated by insects. 由于花粉粒在其长距离的运输过程中所要面临的潜在危险是巨大的，按上述观点来看，由风授粉的植物补偿了通过偶发事件而伴随造成的花粉损失。其途径是，制造出大于昆虫授粉的植物种类所产生的花粉量的一至三个数量级的花粉量。 3.For example，the spiral arrangement of scale-bract complexes onovule-bearing pine cones，where the female reproductive organs ofconifers are located，is important to the production of airflow patterns that spiral over the cones surfaces，there by passing airbornepollen from one scale to the next. 例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。 |
